3 Claims.

The present invention relates to card holding attachments and has for anobject thereof the provision of a card holding attachment adapted fordetachable mounting on the dialing wheel of an automatic telephone tosimplify the dialing of a selected station.

Another object of the invention resides in the provision of such anattachment which will enable dialing without reference to the dialcharacters or a directory and eliminate the likelihood of confusion anderror.

Still another object is to provide a holder member which is adapted fordetachable connection with the conventional structure of a dialtelephone.

A still further object is the provision of a dialing card removablyfitted in the holder member.

Other objects and advantages of the invention will be apparent duringthe course of the following description.

In the drawing, forming part of the specification, and wherein likereference characters designate corresponding parts;

Figure 1 is a top plan view of a telephone dial showing the inventionmounted thereon,

Figure 2 is a sectional view through the same taken on line 2-4 ofFigure 1,

Figures 3 and 4 are enlarged perspective views of the card and holderrespectively in separated positions, and

Figure 5 is a plan view showing the reverse side of the card.

Referring to the drawing, which illustrates one example of theinvention, B denotes the base of a conventional automatic telephoneequipped with the usual dial disk D having circularly arranged letterand numeral characters and the oscillatable wheel W provided with thecustomary apertures P disposed to register with the dial characters.This wheel ordinarily has a raised circular boss-like projection C onits center ortion and is turned with reference to a fixed arm Fextending over the circumferential margin.

My invention has particular reference to an attachment which is to bemounted on the wheel W and advantageously in association with the boss Cthereon. With this in view a holder member H), which may be in the formof a cylindrical sleeve-like body, has an internal diametersubstantially corresponding to the external diameter of the wheel boss Cdesigned to be slidably and snugly fitted to embrace the boss.Approximately midway of its ends the sleeve ID has fixedly mountedtherein a transversely disposed rigid partition plate I l in the form ofa disk.conforming to the interior of the sleeve. On one point of theexterior of the sleeve is secured a radially projecting lug [3 arrangedto contact the arm F.

.This cup-like body is adapted to carry, in its upper socket, a card l5which may be constructed of stiff cardboard or the like and which isessentially disk-shaped to frictionally fit within the circumferentialwall of the socket and against the partition l I. The circular card I5is formed with a tongue l6 projecting radially from its periphery andadapted slidably to engage a rectangular recess or notch 11 in the upperpart of the circumferential body wall to preclude angular displacementof the card when seated in its socket. As shown at Figures 1 and 3, theface of the card which is uppermost in use, has marked thereon arelatively small concentric circle [8 from which radiate straight linesl9 dividing the face into segments 20 corresponding in number to anddisposed to assume radial registry with the dial character exposingaperture P when it is properly seated with the tongue protruding throughthe holder notch. On its reverse or under face the card is to be markedwith station designating indicia, as for example the name of apredetermined person and the call letters of the central oflice andfigures or numbers constituting the characters identifying his station.Below these characters are identifying numerals sequentially numberingthe respective characters from left to right in the order of dialing. Insegments 20 of the centrally disposed card l5, corresponding to therespective characters identified thereby are the identifying numerals,indicating the sequence in which wheel W is turned from its normalposition to the stop arm F for each designated aperture, as in the usualdialing operation.

Thus, the holder member may be readily fitted on any dial telephone, thelug i3 being disposed to abut the fixed arm for proper positioning. Thecard 15 carried in the holder will also be properly mounted to arrangethe segments thereof in registry with the apertures of the wheel by theplacement of the tongue IS in the notch ll of the holder as shown by thearrow pointing between the. apertures 2 and 3 in Figure 1. The card issusceptible of easy removal by gripping the tongue with the thumb andforefinger. Suitably marked cards of different parties may beinterchangeably fitted in the holder.

Therefore, the attachment, which may be easily carried in an ordinarygarment pocket, will greatly facilitate the operation of dialtelephoning of selected parties and practically eliminate the loss andinconvenience occasioned by erroneous calls.

' Having thus described my invention, I claim: 1. In a device of thecharacter described, the combination which comprises a'cylindricalsleeve, a transverse partition wall for said sleeve defining an upperand a lower recess therein, said lower recess being adapted tofrictionally engage the central boss of a dial telephone and said upperrecess being adapted to hold a card bearing indicia 'denoting theoperative sequence of ,actuating apertures of .the dia'ling *wheel offsaid telephone for calling a station, means for preventing rotation ofthe card within the sleeve and means on said sleev to determine therelative angular position of the sleeve with respect to said boss. v

2. In a device of the character described, -the combination whichcomprises a ."short cylindrical sleeve having an inner diametersubstantially corresponding to the outer diameter of the central boss of 'a dial telephone, 'a ipartition :wall :in :said sleeve having 1135plane at right angles 'to the axis o'f the sleeverami rdefiriinga pairof cupshaped recesses therein, cone :of said rrece'sses being *adaptedto ifrictionally engage said :boss, the

'other "of said :recesses :being adapted to efricti'onally hold a wizard'bearing iiialing instructions thereon, a lug protruding from saidsleeve .-into cooperating position with the ifinger stop arm of thetelephone to locate th sleeve on said boss, and a notch in thecard-holding portion of said sleeve adapted to cooperate with a tongueof said card to fix the position of the card in said recess.

3. In a portable attachment for dial telephones, the combination whichcomprises a short cylindrical sleev having an inner diametersubstantially corresponding to the outer diameter of the central boss ofa telephone dial, a partition wall in said sleeve having its plane ialtright angles to the axis of the sleeve and defining a pair of cup-shapedrecesses therein, one of said'recesses being adapted to readilyremovably engage said ibossyiihe iother of said recesses being adaptedto readily .removably hold a plurality of generally circular cards, eachof said cards bearing nu- :aneralls-inradial:registry with certain ofthe apertures of the dialing wheel and denoting the proper sequence oftheir actuation to call a desired :station, a :lug externally protrudingfrom said sleeve and ,abutting against the ,ifinger stop arm of \thetelephone to determine the {angular position of;said1sleeve with respectto said boss, and a anotch in *the az'deholding portion of said sleeveadapted to cooperate with :a tongue ex- ;tendingrfiromsaidcards 'to fixtheiposition-nof the :cards E'iIl v said recess.
